Miscarriage

Hiya I'm just looking for some advice if it's available?

I had a missed miscarriage Sunday passed , it was my first pregnancy, my baby passed at 8 weeks I carried them till 12 still going through it , I know for sure I eventually want to try again but anyone who has gone through the same did you ask for any tests to be done before trying again , I am so so scared of it ahooening again I feel like I'm looking for answers for my miscarriage when there is none and I just don't want it to happen again 😔

Did you have a successful 2nd pregnancy from your experience?
